The neural oscillatory mechanism underlying human brain fingerprint recognition using a portable EEG acquisition device.

In recent years, brainprint recognition has emerged as a novel method of personal identity verification. Although studies have demonstrated the feasibility of this technology, some limitations hinder its further development into the society, such as insufficient efficiency (extended wear time for multi-channel EEG cap), complex experimental paradigms (more time in learning and completing experiments), and unclear neurobiological characteristics (lack of intuitive biomarkers and an inability to eliminate the impact of noise on individual differences). Overall, these limitations are due to the incomplete understanding of the underlying neural mechanisms. Therefore, this study aims to investigate the neural mechanisms behind brainwave recognition and simplify the operation process. We recorded prefrontal resting-state EEG data from 40 participants, which is followed up over nine months using a single-channel portable brainwave device. We found that portable devices can effectively and stably capture the characteristics of different subjects in the alpha band (8-13Hz) over long periods, as well as capturing their individual differences (no alpha peak, 1 alpha peak, or 2 alpha peaks). Through correlation analysis, alpha-band activity can reveal the uniqueness of the subjects compared to others within one minute. We further used a descriptive model to dissect the oscillatory and non-oscillatory components in the alpha band, demonstrating the different contributions of fine oscillatory features to individual differences (especially amplitude and bandwidth). Our study validated the feasibility of portable brainwave devices in brainwave recognition and the underlying neural oscillation mechanisms. The fine characteristics of various alpha oscillations will contribute to the accuracy of brainwave recognition, providing new insights for the development of future brainwave recognition technology.

A review of the clinical efficacy of FDA-approved antibody‒drug conjugates in human cancers.

While strategies such as chemotherapy and immunotherapy have become the first-line standard therapies for patients with advanced or metastatic cancer, acquired resistance is still inevitable in most cases. The introduction of antibody‒drug conjugates (ADCs) provides a novel alternative. ADCs are a new class of anticancer drugs comprising the coupling of antitumor mAbs with cytotoxic drugs. Compared with chemotherapeutic drugs, ADCs have the advantages of good tolerance, accurate target recognition, and small effects on noncancerous cells. ADCs occupy an increasingly important position in the therapeutic field. Currently, there are 13 Food and Drug Administration (FDA)‒approved ADCs and more than 100 ADC drugs at different stages of clinical trials. This review briefly describes the efficacy and safety of FDA-approved ADCs, and discusses the related problems and challenges to provide a reference for clinical work.

Ionic Pairs-Engineered Fluorinated Covalent Organic Frameworks Toward Direct Air Capture of CO2.

The covalent organic frameworks (COFs) possessing high crystallinity and capability to capture low-concentration CO2 (400 ppm) from air are still underdeveloped. The challenge lies in simultaneously incorporating high-density active sites for CO2 insertion and maintaining the ordered structure. Herein, a structure engineering approach is developed to afford an ionic pair-functionalized crystalline and stable fluorinated COF (F-COF) skeleton. The ordered structure of the F-COF is well maintained after the integration of abundant basic fluorinated alcoholate anions, as revealed by synchrotron X-ray scattering experiments. The breakthrough test demonstrates its attractive performance in capturing (400 ppm) CO2 from gas mixtures via O─C bond formation, as indicated by the in situ spectroscopy and operando nuclear magnetic resonance spectroscopy using 13C-labeled CO2 sources. Both theoretical and experimental thermodynamic studies reveal the reaction enthalpy of ≈-40 kJ mol-1 between CO2 and the COF scaffolds. This implies weaker interaction strength compared with state-of-the-art amine-derived sorbents, thus allowing complete CO2 release with less energy input. The structure evolution study from synchrotron X-ray scattering and small-angle neutron scattering confirms the well-maintained crystalline patterns after CO2 insertion. The as-developed proof-of-concept approach provides guidance on anchoring binding sites for direct air capture (DAC) of CO2 in crystalline scaffolds.

Dynamic causal modeling of cerebello-cerebral connectivity when sequencing trait-implying actions.

Prior studies suggest that the cerebellum contributes to the prediction of action sequences as well as the detection of social violations. In this dynamic causal modeling study, we explored the effective connectivity of the cerebellum with the cerebrum in processing social action sequences. A first model aimed to explore functional cerebello-cerebral connectivity when learning trait/stereotype-implying action sequences. We found many significant bidirectional connectivities between mentalizing areas of the cerebellum and the cerebrum including the temporo-parietal junction (TPJ) and medial prefrontal cortex (mPFC). Within the cerebrum, we found significant connectivity between the right TPJ and the mPFC, and between the TPJ bilaterally. A second model aimed to investigate cerebello-cerebral connectivity when conflicting information arises. We found many significant closed loops between the cerebellum and cerebral mentalizing (e.g. dorsal mPFC) and executive control areas (e.g. medial and lateral prefrontal cortices). Additional closed loops were found within the cerebral mentalizing and executive networks. The current results confirm prior research on effective connectivity linking the cerebellum with mentalizing areas in the cerebrum for predicting social sequences, and extend it to cerebral executive areas for social violations. Overall, this study emphasizes the critical role of cerebello-cerebral connectivity in understanding social sequences.

Clinical efficacy of stromal vascular fraction gel in the treatment of mature striae distensae.

BACKGROUND: Striae Distensae (SD) is a common dermatological lesion. The mechanism of formation is unclear, the prevailing theory is mechanical pulling of the skin and hormonal changes. Traditional SD treatment methods include topical drugs, photoelectric therapy, stripping and others, but each has limitations. Stromal vascular fraction gel (SVF-gel) is a filler physically prepared from granular fat, enriched with adipose-derived stem cells (ADSCs) and extracellular matrix (ECM). A good effect in the treatment of neck lines, wounds, acne, and other aspects. SD formation and treatment goals are comparable to those of neck lines. In this study, SVF-gel filling will be used to treat mature SD, and its effectiveness and safety will be discussed in detail. METHODS: From December 2019 to June 2022, recruit patients who want to treat SD caused by obesity or pregnancy among those who have "autologous fat aspiration" to change their body shape. Preoperatively, the area to be treated for SD was marked, autologous fat aspiration was performed, and the aspirated fat was prepared as SVF-gel and filled into the preoperatively marked SD. All patients had preoperative and postoperative follow-up with planar photographs and VISIA skin analyzer photographs to assess surgical results and safety from subjective and objective perspectives. RESULTS: A total of 36 patients were enrolled, with 31 of them successfully followed up on. The mean Global Aesthetic Improvement Scale (GAIS) score six months after surgery was 1.87 ± 0.03. At six months postoperatively, the overall patient satisfaction rate was 90%. The depth, area, and color of SD improved six months after surgery, and no serious complications occurred in any of the patients. CONCLUSIONS: SVF-gel is a safe and effective method of improving mature SD and can be used as a clinical treatment option.

Effectiveness of Platelet-Rich Plasma in the Treatment of Androgenic Alopecia: A Meta-Analysis.

BACKGROUND: Androgenetic alopecia (AGA) is a common yet difficult-to-treat condition, which is an important psychosocial problem. Platelet-rich plasma (PRP) therapy has been considered as a promising treatment for AGA. However, the current evidence on the efficacy of PRP for treating AGA is still controversial. This study evaluated the efficacy of PRP monotherapy in the treatment of AGA. METHODS: We searched PubMed, Embase, Cochrane Library and Web of Science to collect randomized controlled trials on use of PRP in AGA for a meta-analysis. RESULTS: Ten trials with a total 555 treatment units were identified. The hair density in PRP group was significantly higher than control group [MD = 25.09, 95%CI: 9.03-41.15, p = 0.002], but there was no significant difference in hair diameter between two groups [SMD = 0.57, 95%CI: - 0.23 to 1.38, p = 0.16]. Subgroup analyses indicated that hair density was significantly higher among the male-only trials than in the mixed-sex samples (p = 0.02). In addition, neither the split-head design nor the year of publication affected hair density (p = 0.05, p = 0.06). However, hair density was significantly higher in trials with a sample size less than 30 (p = 0.0004). CONCLUSIONS: PRP treatment increased hair density in participants with AGA, but not hair diameter. In terms of hair density, PRP elicits stronger effects in male patients. There was a trend toward differed treatment effect by gender with PRP injection, which warrants further investigation. Especially in the case of female.

Construction of Nitrogen-abundant Graphyne Scaffolds via Mechanochemistry-Promoted Cross-Linking of Aromatic Nitriles with Carbide Toward Enhanced Energy Storage.

The 2D graphyne-related scaffolds linked by carbon-carbon triple bonds have demonstrated promising applications in the field of catalysis and energy storage due to their unique features including high conductivity, permanent porosity, and electron-rich properties. However, the construction of related scaffolds is still mainly limited to the cross-linking of CaC2 with multiple substituted aromatic halogens and there is still a lack of efficient methodology capable of introducing high-concentration heteroatoms within the architectures. The development of alternative and facile synthesis procedures to afford nitrogen-abundant graphyne materials is highly desirable yet challenging in the field of energy storage, particularly via the facile mechanochemical procedure under neat and ambient conditions. Herein, graphyne materials with abundant nitrogen-containing species (nitrogen content of 6.9-29.3 wt.%), tunable surface areas (43-865 m2  g-1 ), and hierarchical porosity are produced via the mechanochemistry-driven pathway by deploying highly electron-deficient multiple substituted aromatic nitriles as the precursors, which can undergo cross-linking reaction with CaC2 to afford the desired nitrogen-doped graphyne scaffolds efficiently. Unique structural features of the as-synthesized materials contributed to promising performance in supercapacitor-related applications, delivering high capacitance of 254.5 F g-1 at 5 mV s-1 , attractive rate performance, and good long-term stability.

Harnessing the Hybridization of a Metal-Organic Framework and Superbase-Derived Ionic Liquid for High-Performance Direct Air Capture of CO2.

Direct air capture (DAC) of CO2 has emerged as the most promising "negative carbon emission" technologies. Despite being state-of-the-art, sorbents deploying alkali hydroxides/amine solutions or amine-modified materials still suffer from unsolved high energy consumption and stability issues. In this work, composite sorbents are crafted by hybridizing a robust metal-organic framework (Ni-MOF) with superbase-derived ionic liquid (SIL), possessing well maintained crystallinity and chemical structures. The low-pressure (0.4 mbar) volumetric CO2 capture assessment and a fixed-bed breakthrough examination with 400 ppm CO2 gas flow reveal high-performance DAC of CO2 (CO2 uptake capacity of up to 0.58 mmol g-1 at 298 K) and exceptional cycling stability. Operando spectroscopy analysis reveals the rapid (400 ppm) CO2 capture kinetics and energy-efficient/fast CO2 releasing behaviors. The theoretical calculation and small-angle X-ray scattering demonstrate that the confinement effect of the MOF cavity enhances the interaction strength of reactive sites in SIL with CO2 , indicating great efficacy of the hybridization. The achievements in this study showcase the exceptional capabilities of SIL-derived sorbents in carbon capture from ambient air in terms of rapid carbon capture kinetics, facile CO2 releasing, and good cycling performance.

A Functional Atlas of the Cerebellum Based on NeuroSynth Task Coordinates.

Although the human cerebellum has a surface that is about 80% of that of the cerebral cortex and has about four times as many neurons, its functional organization is still very much uncharted. Despite recent attempts to provide resting-state and task-based parcellations of the cerebellum, these two approaches lead to large discrepancies. This article describes a comprehensive task-based functional parcellation of the human cerebellum based on a large-scale functional database, NeuroSynth, involving an unprecedented diversity of tasks, which were reliably associated with ontological key terms referring to psychological functions. Involving over 44,500 participants from this database, we present a parcellation that exhibits replicability with earlier resting-state parcellations across cerebellar and neocortical structures. The functional parcellation of the cerebellum confirms the major networks revealed in prior work, including sensorimotor, directed (dorsal) attention, divided (ventral) attention, executive control, mentalizing (default mode) networks, tiny patches of a limbic network, and also a unilateral language network (but not the visual network), and the association of these networks with underlying ontological key terms confirms their major functionality. The networks are revealed at locations that are roughly similar to prior resting-state cerebellar parcellations, although they are less symmetric and more fragmented across the two hemispheres. This functional parcellation of the human cerebellum and associated key terms can provide a useful guide in designing studies to test specific functional hypotheses and provide a reference for interpreting the results.

U-type soft tissue lifting: A new composited technique for reversing lower eyelid and midfacial aging.

BACKGROUND: Facial rejuvenation is becoming more and more popular, particularly among middle-aged persons. There are currently many techniques for improving the aforementioned situations, but each has its drawbacks. Our study aimed to discuss the treatment effect of a composited technique for reversing both lower eyelid and midface aging. METHODS: The patient's face was designed and measured before surgery. During surgery, a traditional lower blepharoplasty incision was made. The layer between the orbital septum and the orbicularis oculi muscle was separated to approximately 4-5 mm below the infraorbital, then the orbital septum and orbicularis retaining ligament were found to be released. A self-made suspension curving needle subconsciously passed through the brim of the superficial cheek fat pad via the "U-type" path and raised them to the proper location. Then sutured them to the infraorbital rim periosteum, as well as the suborbicularis oculi fat (SOOF) and the orbital septum fat. Secured the outside canthus to keep the lower lid position stable. RESULTS: From February 2020 to November 2022, 106 patients underwent the new surgical procedure and were successfully followed up for 20 ± 6.5 months postoperatively. The mean GAIS score was 2.42 ± 0.78, patient satisfaction rate was 95%. All of the Barton grades were decreased. The nasal base level suspension points were elevated to a level of 5 ± 2 mm. 3D measurement data revealed significant improvements. CONCLUSIONS: The composited technique is a safe and effective way to reverse the aging of the lower eyelid and midface.

Ultrasonication-Induced Strong Metal-Support Interaction Construction in Water Towards Enhanced Catalysis.

The development of facile methodologies to afford robust supported metal nanocatalysts under mild conditions is highly desirable yet challenging, particularly via strong metal-support interactions (SMSI) construction. State-of-the-art approaches capable of generating SMSI encapsulation mainly focus on high temperature annealing in reductive/oxidative atmosphere. Herein, ultra-stable metal nanocatalysts based on SMSI construction were produced by leveraging the instantaneous high-energy input from ultrasonication under ambient conditions in H2 O, which could rapidly afford abundant active intermediates, Ti3+ ions, and oxygen vacancies within the scaffolds to induce the SMSI overlayer formation. The encapsulation degree could be tuned and controlled via the reducibility of the solvents and the ultrasonication parameters. This facile and efficient approach could be further extended to diverse metal oxide supports and noble metal NPs leading to enhanced performance in hydrogenation reactions and CO2 conversion.

Construction of Boron- and Nitrogen-Enriched Nanoporous π-Conjugated Networks Towards Enhanced Hydrogen Activation.

Boron-enriched scaffolds have demonstrated unique features and promising performance in the field of catalysis towards the activation of small gas molecules. However, there is still a lack of facile approaches capable of achieving high B doping and abundant porous channels in the targeted catalysts. Herein, construction of boron- and nitrogen-enriched nanoporous π-conjugated networks (BN-NCNs) was achieved via a facile ionothermal polymerization procedure with hexaazatriphenylenehexacarbonitrile [HAT(CN)6 ] sodium borohydride as the starting materials. The as-produced BN-NCN scaffolds were featured by high heteroatoms doping (B up to 23 wt. % and N: up to 17 wt. %) and permanent porosity (surface area up to 759 m2 g-1 mainly contributed by micropores). With the unsaturated bonded B species acting as the active Lewis acid sites and defected N species acting as the active Lewis base sites, those BN-NCNs delivered attractive catalytic performance towards H2 activation/dissociation in both gaseous and liquid phase, acting as efficient metal-free heterogeneous frustrated Lewis pairs (FLPs) catalysts in hydrogenation procedures.

Effects of cadmium contamination on bacterial and fungal communities in Panax ginseng-growing soil.

BACKGROUND: Cadmium (Cd) contamination in soil poses a serious safety risk for the development of medicine and food with ginseng as the raw material. Microorganisms are key players in the functioning and service of soil ecosystems, but the effects of Cd-contaminated ginseng growth on these microorganisms is still poorly understood. To study this hypothesis, we evaluated the effects of microorganisms and Cd (0, 0.25, 0.5, 1.0, 2.0, 5.0, and 10.0 mg kg-1 of Cd) exposure on the soil microbial community using Illumina HiSeq high-throughput sequencing. RESULTS: Our results indicated that Cd-contaminated soil affected the soil microbial diversity and composition, and bacterial diversity was affected more than fungal diversity in Cd-contaminated soil, especially according to Shannon indices. The abundance of the soil microbial community decreased and the composition changed according to the relative abundances at the phylum level, including those of Saccharibacteria and Gemmatimonadetes in bacteria and Mortierellomycota in fungi. The LEfSe algorithm was used to identify active biomarkers, and 45 differentially abundant bacterial taxonomic clades and 16 differentially abundant fungal taxonomic clades were identified with LDA scores higher than 4.0. Finally, a heatmap of Spearman's rank correlation coefficients and canonical discriminant analysis (CDA) indicated that some key biomarkers, Arenimonas, Xanthomonadales, Nitrosomonadaceae, Methylophilales, Caulobacterales, Aeromicrobium, Chitinophagaceae, Acidimicrobiales, Nocardioidaceae, Propionibacteriales, Frankiales, and Gemmatimonadaceae, were positively correlated with the total and available Cd (p<0.05) but negatively correlated with AK, AP, and pH (p<0.05) in the bacterial community. Similarly, in the fungal community, Tubaria, Mortierellaceae, and Rhizophagus were positively correlated with the total and available Cd but negatively correlated with AK, AP, TK, and pH. CONCLUSION: Cd contamination significantly affected microbial diversity and composition in ginseng-growing soil. Our findings provide new insight into the effects of Cd contamination on the microbial communities in ginseng-growing soil.

The Involvement of the Posterior Cerebellum in Reconstructing and Predicting Social Action Sequences.

Recent advances in social neuroscience have highlighted the critical role of the cerebellum and especially the posterior cerebellar Crus in social mentalizing (i.e., theory of mind). Research in the past 5 years has provided growing evidence supporting the view that the posterior cerebellum builds internal action models of our social interactions to predict how other people's actions will be executed, and what our most likely responses to these actions will be. This paper presents an overview of a series of fMRI experiments on novel tasks involving a combination of (a) the learning or generation of chronological sequences of social actions either in an explicit or implicit manner, which (b) require social mentalizing on another person's mental state such as goals, beliefs, and implied traits. Together, the results strongly confirm the central role of the posterior cerebellar Crus in identifying and automatizing action sequencing during social mentalizing, and in predicting future action sequences based on social mentalizing inferences about others. This research program has important implications: It provides for the first time (a) fruitful starting points for diagnosing and investigating social sequencing dysfunctions in a variety of mental disorders which have also been related to cerebellar dysfunctions, (b) provides the necessary tools for testing whether non-invasive neurostimulation targeting the posterior cerebellum has a causal effect on social functioning, and (c) whether these stimulation techniques and training programs guided by novel cerebellar social sequencing insights, can be exploited to increase posterior cerebellar plasticity in order to alleviate social impairments in mental disorders.

CgRab1 regulates Cgcathepsin L1 expression and participates in the phagocytosis of haemocytes in oyster Crassostrea gigas.

Rab protein plays an important role in a variety of cellular activities, especially the fusion process of the inner membrane during endocytosis. In the present study, a Rab1 protein (CgRab1) was identified from the Pacific oyster Crassostrea gigas. The full-length cDNA sequence of CgRab1 was of 2248 bp with an open reading frame of 618 bp, encoding a polypeptide of 205 amino acids containing a Rab domain. The deduced amino acid sequence of CgRab1 shared 94.2% and 89.3% identity with Rab1 from Pomacea canaliculata and Homo sapiens respectively. In the phylogenetic tree, CgRab1 was firstly clustered with the Rab1s from Aplysia californica and Pomacea canaliculata to form a sister group with Rab1 from invertebrates. The recombinant CgRab1 protein (rCgRab1) was able to bind GTP. The mRNA transcripts of CgRab1 were highly expressed in oyster haemocytes, and its expression level in oyster haemocytes was significantly up-regulated at 24 h after the stimulations with Vibro splendidus, which was 2.43-fold (p < 0.01) of that in the control group. After the expression of CgRab1 was knocked down (0.38-fold of that in EGFP-RNAi experimental group) by RNAi，the protein expression of Cgcathepsin L1 were reduced (0.63-fold, p < 0.01) compared with that in EGFP-RNAi experimental group. The phagocytic rate and phagocytic index of haemocytes in CgRab1-RNAi oysters decreased after V. splendidus stimulation, which was 0.50-fold (p < 0.01) and 0.58-fold (p < 0.01) of that in EGFP-RNAi experimental group. These results indicated that CgRab1 was involved in the process of haemocytes phagocytosis by regulating the expression of Cgcathepsin L1 in oyster C. gigas.

The characterization of an agranulocyte-specific marker (CgCD9) in the Pacific oyster Crassostrea gigas.

The agranulocytes in the Pacific oyster Crassostrea gigas are a group of haemocytes that are significantly different from semi-granulocytes and granulocytes on the morphology. Agranulocytes are the smallest haemocytes characterized by a spherical shape, the largest ratio of nucleus to cytoplasm, and no granules in the cytoplasm. The lack of unique cell surface markers impedes the isolation of agranulocytes from total haemocytes. Previous transcriptome sequencing analysis of three subpopulations of haemocytes revealed that a homologue of CD9 (designed as CgCD9) was highly expressed in agranulocytes of oyster C. gigas (data not shown). In the present study, CgCD9 was identified to share a similarity of 60% with other vertebrates CD9s, and it harbored a typical four transmembrane domain and a conserved Cys-Cys-Gly (CCG) motif. The mRNA transcript of CgCD9 was found to be highly expressed in agranulocytes, which was 6.63-fold (p < 0.05) and 3.68-fold (p < 0.05) of that in granulocytes and semi-granulocytes, respectively. A specific monoclonal antibody of CgCD9 (named 3D8) was successfully prepared by traditional hybridoma technology, and a single positive band at 25.2 kDa was detected in the haemocyte proteins by Western Blotting, indicating that this monoclonal antibody exhibited high specificity and sensitivity to CgCD9 protein. The ELISA positive value of 3D8 monoclonal antibody to recognize agranulocytes, semi-granulocytes and granulocytes was 17.35, 4.48 and 1.55, respectively, indicating that monoclonal antibody was specific to agranulocytes. Immunocytochemistry assay revealed that CgCD9 was specifically distributed on the membrane of agranulocytes. Using immunomagnetic beads coated with 3D8 monoclonal antibody, CgCD9+cells with a purity of 94.53 ± 5.60% were successfully isolated with a smaller diameter, a larger N:C ratio and no granules in cytoplasm, and could be primary culture in the modified L-15 medium in vitro. Collectively, these results suggested that CgCD9 was a specific cell surface marker for agranulocytes, which offered a tool for high-purity capture of agranulocytes from total haemocytes in C. gigas.

Evaluation of Pathogenic Fusarium spp. Associated with Soybean Seed (Glycine max) in Hubei Province, China.

Soybean (Glycine max L.) seeds showing serious symptoms from rotted pods were collected from fields during the harvesting period (July to August 2020) in Taihu Farm, Jingzhou City, Hubei Province, China. Fusarium strains were frequently encountered during fungal isolation. According to the morphology and prepathogenicity tests, six strains showing variable effects on the seeds were selected for identification based on morphology and multilocus phylogenetic analysis of the internal transcribed spacer (ITS) region of the ribosomal DNA, translation elongation factor (EF-1α), calmodulin (CAM), ß-tubulin (TUB), and partial RNA polymerase second largest subunit (RPB2), and to evaluate the pathogenic abilities on seed, root, and pod. The results indicated that the strains contained two species (Fusarium fujikuroi and F. proliferatum) in the Fusarium fujikuroi species complex (FFSC) and two species (F. luffae and F. sulawense) from the Fusarium incarnatum-equiseti species complex (FIESC). The two species of FFSC were more aggressive than those of FIESC on soybean seed, root, and pod. Among the strains, F. proliferatum YZU 201408 exhibited the most pathogenicity on all tests, with 72.2 to 90% disease severity.

Effect of Positional Changes on Skin Landmarks in Midface Filling.

BACKGROUND: The design lines for midfacial filling shift upward with a patient's position changes from upright to supine during operation. This will cause the actual filled part to deviate from the target area. OBJECTIVES: This authors aimed to evaluate the effect of positional changes on midfacial landmarks and find the optimal body position for midface filling. METHODS: The process involved the grading and evaluation stages. The midfacial laxity of each sample in the evaluation stage was graded into minimal, moderate, and severe by the system established in the grading stage. Measured through the 3-dimensional images in each grade, the vertical distances from landmarks C, D, and E (representing the region of the tear trough, infraorbital area, and nasolabial fat pad, respectively) to the horizontal line of the inner canthus and depth of nasolabial fold at an angle of 90° were separately compared with those from the other angles (60°, 45°, 30°, and 0°) of the operating table. RESULTS: In the minimal midfacial laxity group, all 3 landmarks significantly moved upward when the angle decreased to 30°. However, landmark E of the moderate and severe and landmark D of the severe midfacial laxity groups both significantly moved upward when the angle decreased to 45°. The depth of the nasolabial fold at a 45° angle was significantly less than that at a 90° angle in the moderate and severe groups. CONCLUSIONS: In midface filling, a patient's body position should be optimally selected according to the midfacial laxity and filling area.

Fully Conjugated Poly(phthalocyanine) Scaffolds Derived from a Mechanochemical Approach Towards Enhanced Energy Storage.

Phthalocyanines (Pc)-derived materials represent an attractive category of porous organic scaffolds featured by extensive π-conjugated networks, but their construction is still limited to the solution-based pathways, producing materials with inferior conductivity and porosity. Herein, a mechanochemistry-driven approach was developed leveraging the on-surface polymerization of aromatic nitrile monomers with ortho-positioned dicyano groups in the presence of metal catalysts (magnesium, zinc, or aluminum) under neat and ambient conditions. Diverse Pc-functionalized conjugated porous networks (Pc-CPNs) were obtained featured by extensively and fully π-conjugated skeletons, high surface areas, and hierarchical porosities. The monomers in this mechanochemical approach could be extended to those difficult to be handled in solution-based procedures. The Pc-CPNs displayed attractive electrochemical performance as supercapacitor and anodes in batteries, together with superb long-term stability.

The effect of human settlement temperature and humidity on the growth rules of infected and recovered cases of COVID-19.

This study investigated the impact of humidity and temperature on the spread of COVID-19 (SARS-CoV-2) by statistically comparing modelled pandemic dynamics (daily infection and recovery cases) with daily temperature and humidity of three climate zones (Mainland China, South America and Africa) from January to August 2020. We modelled the pandemic growth using a simple logistic function to derive information of the viral infection and describe the growth of infected and recovered cases. The results indicate that the infected and recovered cases of the first wave were controlled in China and managed in both South America and Africa. There is a negative correlation between both humidity (r = - 0.21; p = 0.27) and temperature (r = -0.22; p = 0.24) with spread of the virus. Though this study did not fully encompass socio-cultural factors, we recognise that local government responses, general health policies, population density and transportation could also affect the spread of the virus. The pandemic can be managed better in the second wave if stricter safety protocols are implemented. We urge various units to collaborate strongly and call on countries to adhere to stronger safety protocols in the second wave.
